Georeference

Get the XYZ position (in the ECEF frame) of a depth sounding (in the WGS84 frame)

# Example values
# latitude = math.radians(48.4525) //decimal degrees
# longitude = math.radians(-68.5232) //decimal degrees
# ellipsoidal_height = -28 //meters
# heading = math.radians(350)
# pitch = math.radians(0.5)
# roll = math.radians(1.5)
# depth = 5 //meters
# offset_x = 1 //meters
# offset_y = 2 //meters
# offset_z = 3 //meters

import georeference
g = georeference.Georeference()
result = g.compute(latitude,longitude,ellipsoidal_height,heading,pitch,roll,depth,offset_x,offset_y,offset_z)

Uncertainty

Get the uncertainty associated with an XYZ position (in the ECEF frame) of a depth sounding (in the WGS84 frame)

# Example values
# latitude = math.radians(48.4525) //decimal degrees
# longitude = math.radians(-68.5232) //decimal degrees
# ellipsoidal_height = -28 //meters
# heading = math.radians(350)
# pitch = math.radians(0.5)
# roll = math.radians(1.5)
# depth = 5 //meters
# offset_x = 1 //meters
# offset_y = 2 //meters
# offset_z = 3 //meters
# latitude_sigma = 0.00001
# longitude_sigma = 0.0001
# ellipsoidal_height_sigma = 1
# heading_sigma = 1
# pitch_sigma = 1
# roll_sigma = 1
# depth_sigma = 0.5
# offset_x_sigma = 0.0000001
# offset_y_sigma = 0.0000001
# offset_z_sigma = 0.0000001
